11 claims

Legal claims defining the scope of protection, as filed with the USPTO.

2

2. The method of claim 1, further comprising responsive to the resynchronization process successfully bringing the first volume back into the InSync state, resuming the access to the primary copy of the data stored on the first volume.

3

3. The method of claim 1, wherein the first type of resynchronization process comprises a fast resynchronization process involving the use of an operation log that indicates respective completion status of inflight operations associated with the data replication and differences between the primary copy of the data and a secondary copy of the data maintained by the peered volume.

6

6. The method of claim 4, wherein the time period is selected to avoid input/output disruption from impacting an application associated with the local CG and the remote CG.

8

8. The non-transitory computer-readable storage medium of claim 7, wherein the instructions further cause the distributed storage system to responsive to the resynchronization process successfully bringing the first volume back into the InSync state, resume the access to the primary copy of the data stored on the first volume.

9

9. The non-transitory computer-readable storage medium of claim 7, wherein the first type of resynchronization process comprises a fast resynchronization process involving the use of an operation log that indicates respective completion status of inflight operations associated with the data replication and differences between the primary copy of the data and a secondary copy of the data maintained by the peered volume.

12

12. The non-transitory computer-readable storage medium of claim 10, wherein the time period is selected to avoid input/output disruption from impacting an application associated with the local CG and the remote CG.

13

13. The non-transitory computer-readable storage medium of claim 10, wherein the time period is between 30 and 90 seconds.

15

15. The distributed storage system of claim 14, wherein the instructions further cause the distributed storage system to responsive to the resynchronization process successfully bringing the first volume back into the InSync state, resume the access to the primary copy of the data stored on the first volume.

16

16. The distributed storage system of claim 14, wherein the first type of resynchronization process comprises a fast resynchronization process involving the use of an operation log that indicates respective completion status of inflight operations associated with the data replication and differences between the primary copy of the data and a secondary copy of the data maintained by the peered volume.

19

19. The distributed storage system of claim 17, wherein the time period is selected to avoid input/output disruption from impacting an application associated with the local CG and the remote CG.

20

20. The distributed storage system of claim 17, wherein the time period is between 30 and 90 seconds.
